摘要 |
An adjustable intervertebral implant (100) for implantation into a patient's s?ine in-between first and second adjacent or neighboring vertebrae. The implant may include one or more of the following features : (i) inner (110) and outer (115) members coupled by a radiographically imageable expansion ring (130), (ii) detachable endplates (120,125) coupled to the implant via a polygonal press-fit coupling interface that accommodate a range of lordotic endplates to be applied to the implant using any surgical approach, (iii) an interference pre-loaded set screw (160) for selectively locking the height of the construct, (iv) a radiographically imageable marker (180) for determining the expansion of the implant, and (v) an asymmetric thread coupling (133,190) between the expansion ring and the inner member. |
